Study of the transient nature of classical Be stars using multi-epoch optical spectroscopy
Gourav Banerjee, Blesson Mathew, K. T. Paul +8
Variability is a commonly observed property of classical Be stars (CBe) stars. In extreme cases, complete disappearance of the Hα emission line occurs, indicating a disc-less state…
UVIT view of Centaurus A; a detailed study on positive AGN feedback
Prajwel Joseph, P. Sreekumar, C. S. Stalin +4
$\require{mediawiki-texvc}$ Supermassive black holes at the centre of active galactic nuclei (AGN) produce relativistic jets that can affect the star formation characteristics of t…
Decoding the X-ray flare from MAXI J0709-159 using optical spectroscopy and multi-epoch photometry
Suman Bhattacharyya, Blesson Mathew, Savithri H Ezhikode +10
We present a follow-up study on the recent detection of two X-ray flaring events by MAXI/GSC observations in soft and hard X-rays from MAXI J0709-159 in the direction of HD 54786 (…
Discovery of Quasi Periodic Oscillations in the persistent X-ray emission of Accreting Binary X-ray Pulsar LMC X-4
Ketan Rikame, Biswajit Paul, Pragati Pradhan +1
We report the discovery of quasi-periodic oscillations (QPOs) in the High Mass X-ray Binary (HMXB) pulsar LMC X-4 in its non-flaring (persistent) state using observations with XMM-…
